The “Mean Girls” actress jetted to the South American country on Wednesday as part of a deal to help promote a Brazilian clothing label.

She is due to begin a 90-day stint in a lockdown rehab center in the U.S. to address her issues as punishment for lying to police over a car crash in California last year, but she enjoyed a wild night out in Sao Paulo shortly after landing in Brazil.

An image obtained by editors at TMZ.com depicts a sweaty faced Lohan sitting underneath a table in a nightclub while wearing designer heels and a short black dress.

A report on a local website alleges the actress was hiding from onlookers after being besieged by fans wanting to take photos with her.

Embattled actress Lindsay Lohan has denied reports she was boozing in a California nightclub on Saturday, insisting she spent the evening sipping water at a private dinner.

Last week, the “Mean Girls” star was ordered to serve 90 days in a lock-down rehabilitation center and stay away from drugs, but she was rumored to have enjoyed a wild night out drinking with friends in Santa Monica over the weekend.

However, the 26 year old took to her Facebook page on Sunday to assure fans it was an entirely innocent affair.

She writes, “1) It wasn’t a nightclub – 41 Ocean is a members only dining club… and a private event (and) 2) It was Pellegrino (mineral water)!”

Lohan also sparked speculation of a new romance after she was spotted kissing guitarist Avi Snow at the event, where his band City of the Sun performed.

She adds, “The most important part – the band City of the Sun did any amazing (sic) job last night!”

Lohan has been given until May 2 to enroll in a rehabilitation facility after pleading no contest to charges relating to a car crash in California last summer.

Last Tuesday, the star was forced to dismiss reports suggesting she hit up a nightclub just hours after her courtroom sentencing, when a lookalike was photographed hiding in the back seat of an SUV outside Los Angeles hotspot A/V.

Lindsay Lohan has blasted tabloid and Internet reports suggesting she was intent on clubbing on Monday night, hours after she was ordered to serve 90 days in a lockdown rehab, insisting she’s taking her troubles seriously this time.

Images of a girl purported to be the embattled actress, crouching down in the back seat of an SUV, outside Hollywood nightclub A/V hit the world wide web on Tuesday morning, but Lohan insists the girl in the vehicle isn’t her – and she wasn’t in the mood to party after her latest courthouse showdown.

The actress took to Twitter on Tuesday to defend herself against allegations that she is not taking her punishment seriously enough after accepting a plea agreement to stay out of jail for lying to police officers following a car accident on the Pacific Coast Highway in California last summer.

She wrote, “Guys relax, that was NOT me at A/V or in the … SUV. I’m taking this seriously and focused on the road ahead.

“I stayed in last night, after a pretty long day … and ordered sushi to my hotel. … Don’t believe EVERY little thing you hear, unless you hear it from me.”

And she took the time to thanks fans for sticking by her throughout her troubles, adding, “The support I have gotten, has been great and means alot (sic).”

Reports suggested the girl in the back of the SUV didn’t get out of the vehicle when she realized the club was swarming with paparazzi and instructed a friend to drive off.

Lindsay Lohan has agreed to spend 90 days in a locked-down rehabilitation facility after striking a late plea deal to avoid jail in her latest legal troubles.

The star faced 240 days behind bars amid charges she lied to police following a California car crash last year, accusations which also put her at risk of breaking the terms of her probation for a 2011 jewelry theft conviction.

Trial proceedings against the embattled actress were expected to kick off on Monday morning, but the hearing was pushed back after Lohan turned up at the Los Angeles courthouse 48 minutes late following a series of flight dramas.

Her late arrival allowed her lawyer Mark Heller extra time to negotiate with prosecutors and by the time the case went before Judge James R. Dabney at 11 a.m., the two parties had reached an agreement on a plea deal.

Lohan agreed to serve a 90-day sentence in a treatment facility, complete 30 days of community service in her native New York and undergo 18 months of psychotherapy, which she has already enrolled in. She was also ordered to pay fines and restitution to the other driver involved in the crash last summer.

In exchange for jail alternative, Lohan pleaded no contest to lying to cops and reckless driving. The latter charge also carried a mandatory five days in jail, although prosecutors allowed the actress to include that in her rehab stay and she will therefore not spend any time behind bars.

She also admitted to violating her probation and was given a 180-day jail sentence, which was suspended providing she completes her rehab and community service with no further drama. As part of the deal, Lohan must stay away from drugs and submit to random testing.

Charlie Sheen has offered to mentor troubled Lindsay Lohan, insisting hanging out with him would be better than mixing with her “dress-shredding club buddies.”

The actress has been dealt a series of legal and image blows following a number of poor decisions she has made over the past 18 months.

At present she faces jail time for violating her probation on a jewelry theft charge by allegedly lying to police officers about a 2012 car crash, and she recently came under fire for tearing a designer dress she was loaned for a charity event.

Now Sheen, who has helped Lohan settle tax debts with cash hand-outs, believes his past experiences could be invaluable to the Mean Girls actress.

He tells TMZ.com, “I have a kinship with somebody who clearly needs a mentor, whether she wants one or not. She can continue to hang out with her dress-shredding club buddies, or turn to me for some advice… a guy who’s been down the road as well as every other side trail on the journey.”

He adds, “If she listens, she’ll win. If she doesn’t, that’s on her.”

Sheen and Lohan struck up an unlikely friendship while working together on “Scary Movie 5,” and she will be appearing on an upcoming episode of his sitcom “Anger Management.”

Lindsay Lohan is planning to turn her life around by taking part in intensive psychotherapy sessions and launching a foundation to help troubled youngsters, according to her lawyer.

The “Mean Girls” star is facing probation violation charges, but her attorney Mark Heller has filed a motion requesting the ongoing case be set aside so his client can pursue “certain activities which will benefit her” and enable her to be a “productive and responsible … contributor to society.”

In a letter to the Santa Monica City Attorney, Heller writes, “Lindsay has asked me to facilitate an in-person meeting … not to discuss the merits of her defense of the details of her case, but rather for Lindsay to introduce herself … and express her desire to share her thoughts and help in the process of our determining what the best course would be for her future and to personally affirm her commitment and dedication to fix the problems.”

Heller’s letter, dated February 4, goes on to detail the actress’ plan to bounce back from a recent string of legal troubles.

He states, “Lindsay will gladly be participating in intensive psychotherapy, submitting herself to regular screenings and contributing her time to the production of public-service messages and periodic visits to schools, hospitals and other venues where she may provide inspirational talks, encouraging children to pursue positive goals and avoid bad habits.”

He also notes the 26-year-old is “exploring the establishment of a Lindsay Lohan Foundation” in a bid to “provide a nonprofit program to benefit young people.”

In his motion, Heller asks the court to dismiss charges against Lohan that stem from a car accident in California last June, when she allegedly lied to cops by suggesting she was not behind the wheel of the Porsche.

A judge will make a decision on Heller’s request at a hearing on Friday, reports EOnline.com.

Lindsay Lohan’s lawyer has asked a judge to dismiss an ongoing car crash case over claims the actress was not read her rights before cops questioned her in hospital.

The actress has been accused of lying to police officers for allegedly suggesting she was not driving her Porsche at the time of an accident in California last summer, and the incident has left her facing probation violation charges.

Lohan’s attorney, Mark Heller, has now filed a court motion asking a judge to dismiss the case over allegations the cops who questioned the actress in a Santa Monica hospital failed to issue her with a Miranda warning, which is given to suspects during a custodial interrogation to inform them their statements will be used in criminal proceedings.

In the documents, which were filed in court in California on Friday, Lohan claims the officers told her she was not free to leave or receive further medical treatment until she answered their questions, according to the New York Daily News.

Lohan’s probation stems from her 2011 necklace theft conviction and she has pleaded not guilty to a violation charge.

Lindsay Lohan’s money woes are stacking up after officials slapped the troubled actress with a new tax bill.

The “Mean Girls” star is accused of owing the state of California $56,717 in unpaid income taxes from 2011, reports TMZ.com.

Lohan was recently able to clear her 2009 tax debt after her “Scary Movie 5″ co-star Charlie Sheen handed her a check for $100,000, but she still owes the IRS $140,203 for federal income taxes stemming from 2010.

In December, Lohan’s publicist insisted the star was “working out” a payment deal with IRS authorities after falling behind on her taxes.
